Hello John,

I would be interested to learn more about the mods required to overcome design faults in the Astra TV chassis.

I know there were mods to the ultrasonic remote control system in the relevant models; the plug-in flywheel sync PCB (to overcome video information folder on the LHS, on 625 working); to overcome 405-625 switching delay in converted sets (due to not all heaters being powered up on both line standards) and to enable VHF/625 line working.

I am not aware of any other major mods to the basic chassis......?

Regards,
